Ipomoea batatas-Sweet Potato Vine. This has been growing in the greenhouse plant collection for about a year; we decided to try it outside as a ground cover and it did very well in both locations. Although it was slow to get going, by the second evaluation it was very vigorous in both Fargo and Dickinson. The biggest problem it had was slugs eating the foliage in Fargo.
